SPECIFICATION forming part of Letters Patent No. 505,787, dated September 26, 1893.

Application filed May II 1893. Serial No. 472,530. (No model.) a

To all Lu/tom it may concern;

Be it known that I, ELI FIELDEN, a subject of the Queen of Great Britain and Ireland, residing at No. 293 Rochdale Road, Britannia, near Bacup, in the county of Lancaster, England, have invented an Improved Slategleaner, of which the following is a specificaion.

My invention relates to an improved appliance for cleaning slates or other writing tablets as shown in the accompanying drawings in which a is a water receptacle or reservoir having at one end a holder 7) into which is pushed a sponge c (or a mop made of tow, cotton waste, india rubber, or other material suitable for cleaning slates may be used.) There is no direct access of the water in the receptacle to the sponge or its substitute. At the other end of the receptacle is a diaphragm 61 having one or more perforations a so minute that when at rest no water passes through. When however the appliance is held in the hand and shaken over the slate a few drops of water are ejected whereupon by reversing the appliance in the hand and using the other end the slate may be cleaned.

Surrounding the diaphragm is a rim for conical jacket f for retaining any excess water. The cleaning end may be variously shaped as shown for example in Figs. 2 and 3 Where instead of sponge abent piece of thick cloth or felt is riveted between or over suitable projecting parts at the end of the The water receptacle a Water receptacle.

I to hold it at some distance say a foot or more from a water cock so that the falling jet of Water may fall directly on the perforated diaphragm. The falling jet of water may be obtained by holding a lipped water vessel in one hand and allowing a stream of water to fall onto the diaphragm while the appliance is held in the other hand at some distance below.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

A cleaner for slates and writing tablets provided with a water receptacle, a mop at one end thereof and a perforated diaphragm and raised water retaining jacket at the other, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ELI FIELDEN.
